Abstract: Provided are a polyamic acid resin derived from an aromatic diamine, an aromatic dianhydride, a cycloaliphatic dianhydride and an aromatic diacid dichloride, and a polyamideimide film including polyamideimide derived from an aromatic diamine, an aromatic dianhydride, a cycloaliphatic dianhydride and an aromatic diacid dichloride.

Abstract: Provided are a polyamideimide film, a window cover film, and a display panel including the same. More specifically, a polyamideimide film including an amideimide structure derived from a dianhydride, a diamine, and an aromatic diacid dichloride is provided, wherein a chlorine content in the film is 5 to 33 ppm and a yellow index change amount ?YI is 5 or less, the yellow index change amount being measured in accordance with ASTM E313 after repeating a process of irradiating 0.55 W/m2 of UVA at 340 nm at 40° C. for 20 hours and then blocking UVA for 4 hours three times.

Abstract: The present invention provides a drainage tube introducer wherein while a drainage tube is fitted over an introducing end portion (42) protruding through a pin hole (32) and is introduced through an incision portion (4) into an infected portion (2) in cooperation with the introducing end portion (42), a stop block (52) is pressed by pushing a sleeve (70) frontward, which bends an operating lever (50) made of an elastic material to release the stop block (52) from a stop hole (38). Accordingly, a pin (40) is moved rearward by an elastic member (60) to withdraw the introducing end portion (42) protruding through the pin hole and to separate the drainage tube introduced into the infected portion (2) from the introducing end portion (42).

Abstract: A teletext signal detector and method including a plurality of field memories for storing by screens index page data, a user-designated page storage, an index page storage, an index page storing discriminator, and a display. The teletext signal detecting method comprises the steps of storing teletext information by screens, extracting only a plurality of index pages with respect to screens to sequentially store them, comparing the index pages with a user-designated page, and if they match, displaying the index page on a CRT, and if they do not match, providing a warning of the absence of the index page.
